Covid-19 persists in lung tissue

Researchers found what they describe as a "long-term persistence" of the viral DNA in respiratory cells and in cells lining the blood vessel.

Major structural changes that persist for several months have been observed in the lungs of deceased Covid-19 patients and could help explain long Covid, scientists have said.

The findings, published in the journal Lancet eBioMedicine, are based on a study of the organs of 41 patients who died at the University Hospital of Trieste, Italy, between February and April 2020.
